Paper cuttings made by 17th-century schoolgirls discovered beneath floorboards

My mom lived in a historical house when she was a kid in the 60s. Since then, the house has become a museum. There are a lot of "artifacts" on display that "came from the 1800s" that are actually just toys my moms brothers made. My mom got a good laugh about it when she took me to visit the place.

I'm sure these finds must have dated in some way to verify the authenticity, but I always think back to seeing my uncles toys on display as if they were historical artifacts when I see stuff like this.

Has your mom got in touch with the museum to tell them that, so they can improve? If not why not?

It’s not their mothers responsibility to correct their incompetence, or (imo) more likely negligence and information falsification.
